I added the relevant patch [1] to 10.3-STABLE (r297721) and I = can confirm that that fixed the performance issue.=20 Now, with pkg-1.7.2 for the very same 74 ports and jail reinstallation = is back to 26 seconds: Apr 8 20:04:42 <user.notice> pkg: indexinfo reinstalled: 0.2.4 = -> 0.2.4=20 ... Apr 8 20:05:08 <user.notice> pkg: pkg reinstalled: 1.7.2 -> = 1.7.2=20 Up to now, 10.3-STABLE runs rock solid. I will report if that might = change. Thanks for your engagement and with kind regards, Michael [1] = https://svnweb.freebsd.org/base/head/lib/libc/db/hash/hash.c?view=3Dpatch&= r1=3D297626&r2=3D297625&pathrev=3D297626=20
